Iterating a bnr network

Usage

iterate_bnr(adjm, np, pb, pn, pr)

# S4 method for matrix,numeric,numeric,numeric,numeric
iterate_bnr(adjm, np, pb, pn, pr)

Arguments

adjm: Adjacency matrix
np: numeric vector setting ids for the newborn (i.e. which individual will be replaced with a new one) and a parent(s). Length 2 or 3. If you want to randomly select an id for the newborn (first value) and parents (second and third value), simply use c(0,0) or c(0,0,0). For one parent, the focal individual connects to this parent with probability pb. For two parent values, the individual connects to two parents each with probability pb.
pb: Probability to connect to parent. Default is 1.
pn: Probability to connect to neighbour of parent(s)
pr: Probability to connect to individuals that are not connected to the parent

Value

Returns an iterated version of the supplied adjacency matrix as a numeric matrix.

Details

If you just want to iterate the graph you can use np=c(0,0) or np=c(0,0,0). However, the function does not return the ids of the newborn and the parent(s). If you want to keep track of the ids that are changed, you should provide these as an input to the function.

Examples

# Set up linking parameters:
pb <- 1
pn <- 0.2
pr <- 0.01
# Generate a network based on these parameters
adjm_t0 <- make_bnr(n = 100, np=c(0,0), pb = pb, pn = pn, pr = pr)
# Iterate the network
adjm_t1 <- iterate_bnr(adjm = adjm_t0, np=c(0,0), pb = pb, pn = pn, pr = pr)
